Queensland's peak rural lobby group AgForce is calling on the Federal Government to reinstate legal assistance for graziers with properties under native title claim.

Funding had been provided since 1996 but was slashed late last year.

AgForce spokeswoman Lauren Hewitt says many farmers will be forced to drop out of the expensive and complex process.

"AgForce has been lucky enough to seek a small amount of funding from the State Government to continue that service," she said.

"That will close in the next couple of months and from there on people will have to decide what they want to do.

"For many people that will literally mean withdrawing because they cannot afford the legal representation.

"We are going to see a lot of delays now in the system, we're going to see a lot of confusion because there's no-one there to explain this process and walk people through this process and coordinate it in the way that we were doing very simply and very efficiently."
